Motorists are being urged to take on their morning commute after an icy night. A yellow weather warning is currently in place across Devon this morning (Thursday) as temperatures dropped into the minus figures last night. Devon County Councils 37 frontline gritters were working hard salting the road network last night and into the early hours of this morning. But motorists travelling on untreated roads are urged to take care of icy patches. Councillor Stuart Hughes, DCC Cabinet Member for Highway Management, said: Temperatures are getting lower and this could be the first real icy spell this winter, so people should be exceptionally careful when out and about. Untreated roads may well be icy with a freeze following the showers of rain that are expected, but even treated roads could see ice forming.
